Answer 1

The unit rate for the 5-gallon bucket is $19.49 per gallon and for the 1-gallon bucket is $21.95 per gallon, making the 5-gallon bucket the better buy.

Step-by-step explanation:

To find out which is the better buy between the 5-gallon and 1-gallon buckets of paint, we need to calculate the unit rate for both options. The unit rate is the cost per single unit, which in this case is per gallon of paint.

The cost of the 5-gallon bucket of paint is $97.45. To find the unit rate, we divide the total cost by the number of gallons:

Unit rate for 5-gallon bucket = $97.45 ÷ 5 gallons = $19.49 per gallon.

The cost of the 1-gallon bucket of paint is $21.95, which is the unit rate for the 1-gallon bucket since it is already per 1 gallon.

Given this information, the unit rate for the 5-gallon bucket is $19.49 per gallon, and for the 1-gallon bucket is $21.95 per gallon. Therefore, the 5-gallon bucket is the better buy since it offers a lower cost per gallon.

The correct answer is c) Unit rate: $19.49; 5-gallon bucket is a better buy.
